In the present work an attempt has been made to analyze quantitatively the content of vitexin in Oxalis corniculata leaves and its protective activity on gentamicin and cisplatin induced nephrotic damage in albino rats. Vitexin is 8-beta-D glucopyranosyl apigenin found commonly in Oxalis corniculata, a plant of good repute in Ayurvedic system of medicine. The HPTLC analysis data indicated that the collected Oxalis corniculata leaves contain 289.8 mg/g of vitexin. The leaf methanolic extract of O. corniculata (OCLM) as well as vitexin showed significant protection on gentamicin and cisplatin induced nephrotoxicity in albino rats. Both OCLM and vitexin produced significant scavenging effect upon hydroxyl, lipid peroxide and superoxide, free radicals. OCLM showed better diuretic effect as compared to vitexin.

AbstractObjectivesRauvolfia vomitoria is a medicinal plant used traditionally in Africa in the management of several human diseases including psychosis. However, there is inadequate scientific information on the potency of the phenolic constituents of R. vomitoria leaf in the management of neurodegeneration. Therefore, this study characterized the phenolic constituents and investigated the effects of aqueous and methanolic extracts of R. vomitoria leaf on free radicals, Fe2+-induced lipid peroxidation, and critical enzymes linked to neurodegeneration in rat’s brain in vitro.MethodsThe polyphenols were evaluated by characterizing phenolic constituents using high-performance liquid chromatography coupled with diode array detector (HPLC-DAD). The antioxidant properties were assessed through the extracts ability to reduce Fe3+ to Fe2+; inhibit ABTS, DPPH, and OH radicals and Fe2+-induced lipid peroxidation. The effects of the extracts on AChE and MAO were also evaluated.ResultsThe phenolic characterization of R. vomitoria leaf revealed that there were more flavonoids present. Both aqueous and methanolic extracts of R. vomitoria leaf had inhibitory effects with the methanolic extract having higher significant (p≤0.05) free radicals scavenging ability coupled with inhibition of monoamine oxidases. However, there was no significant (p≤0.05) difference obtained in the inhibition of lipid peroxidation and cholinesterases.ConclusionThis study suggests that the rich phenolic constituents of R. vomitoria leaf might contribute to the observed antioxidative and neuroprotective effects. The methanolic extract was more potent than the aqueous extract; therefore, extraction of R. vomitoria leaf with methanol could offer better health-promoting effects in neurodegenerative condition.

Phytochemical investigations of the methanolic extract of the fruits of Peucedanum grande C. B. Clarke (Apiaceae) led to the identification of three coumarins and a naphthyl labdanoate diarabinoside characterized as 5-hydroxy-6-isopranyl coumarin (1), 5,6-furanocoumarin (2), 7-methoxy-5,6-furanocoumarin (3), and labdanyl-3α-ol-18-(3’’’-methoxy-2’’’- naphthyl-oate)-3α-L-arabinofuranosyl-(2’→1’’)-α-L-arabinofuranoside (4). The structures of these compounds were identified on the basis of spectral data analysis and chemical reactions. The methanolic extract and 4 showed nephroprotective activity against gentamicininduced nephrotoxicity in Wistar rats.

Background: Various factors have been identified as influencing factors of breast cancer. The free radicals can cause increased oxidative stress by negatively affecting the body’s nucleic acids, lipids and proteins leading to various illnesses including cancer. Therefore, this study was aimed at discovering the progress of treatment of breast carcinoma by exploring the connections of the disease with free radical injury.Methods: The present study was conducted among 30 breast carcinoma patients received in the surgery department of BRD Medical College Gorakhpur. Determination of the levels superoxide dismutase (SOD) (the procedure of photoluminescence), catalase (method of Cavarochi) and the lipid peroxidise was done. The results were presented as mean and standard error (SE). P value of <0.05 was considered as statistically significant.Results: Among the total participants, 73% patients had infiltrating ductal carcinoma and 27% patients had intraductal carcinoma. The dismutase levels showed an increase in the post-operative patients for both the groups. The catalase levels and the lipid peroxide levels showed a reduction in the postoperative patients (p<0.05).Conclusions: The present study result showed that the low amounts of SOD and catalase may not be sufficient to detoxify high amounts of free radicals. The administration of catalase could help in reducing the symptoms. Though, low amounts of SOD and catalase may not be sufficient to detoxify high amounts of free radicals. The administration of enzymes could help in the treatment of breast cancer patients.

Background: Diabetes prevalence is estimated to increase annually. Numerous people use traditional medicine, such as India also considered as the diabetic capital in the world. Diabetes is a metabolic disorder characterized by disturbances in lipid, carbohydrate and protein metabolism. The present study to evaluate the antidiabetic potential of coriandrum sativum. linn fruits methanolic extract in streptozocin induced diabetic wistar albino rats model.Methods: Diabetes induction in wistar albino rats by administration of streptozocin (50mg/kg, i.p.) in citrate buffer. 30 wistar albino rats were divided into 5 groups (A, B, C, D, E). Group A: served as normal control, whereas Group B: diabetic control, Group C, D methanolic coriandrum sativum Linn. fruits extract (CSFME) at a dose of 100, 200mg/kg orally, Group E was given standard drug Glibenclamide (0.5mg/kg) orally. All groups are administered for the period of 14 consecutive days and blood sugar levels was measured at regular intervals up to end of the study.Results: This present research study confirms that the test drug compound CSFME has sustained oral hypoglycaemic activity and statistically significant (p ≤0.05) and which is comparable with standard drug Glibenclamide.Conclusions: This research study confirms that the CSFME has antidiabetic activity against streptozocin induced wistar diabetic albino rats. It could be a novel antidiabetic agent and also a dietary adjunct in the type 2 diabetes management and its complication. Further studies are necessary required to confirm the antidiabetic activity of individual phytochemical compounds of Coriandrum sativum.

Cubeba Officinalis is traditionally effective in the treatment of various kidney ailments, and the main adverse effect of tacrolimus is nephrotoxicity. There is no documented evidence about the ameliorative potential of Cubeba Officinalis in tacrolimus induced nephrotoxicity. The main endeavor of the study was to determine the nephroprotective activity of ethanolic extract of Cubeba Officinalis dried fruits against tacrolimus induced nephrotoxicity in Wistar albino rats. The Cubeba Officinalis dried fruits were collected from the local market, and Male albino rats weighing 200-250 g were used for the study. The dose of is lower 200mg/kg, higher dose 400 mg/kg of test drug (EECO) was used, and silymarin is used as the standard at the dose of 20 mg/kg. The animals were divided into five groups, six animals each, which is started prior to oral administration of tacrolimus and continued with the fourteen days tacrolimus treatment. After the whole period of study, the rats were sacrificed, and histopathological studies and biochemical estimations were carried out. The BUN values  were decreased from 33.60±3.84 in nephrotoxic rats to 28.27±2.48 (200mg/kg) and 20.70±0.81 (400mg/kg),creatinine levels from 1.645±0.21 to 0.926±0.19 (200mg/kg) and 0.638±0.07(400 mg/kg),uric acid levels from 1.822±0.249 to 1.092±0.306 (200 mg/kg) and 0.806±0.181 (400 mg/kg) sodium, potassium and chloride levels from 1.607± 0.091, 2.548± 0.293 and 259.8±6.42 to 1.302± 0.169 , 1.023±0.174 and 134.7±9.138 (200mg/kg of EECO) and 0.586±0.092 , 0.831±0.174 and 130.2±2.29 (400mg/kg of EECO). The Ethanolic extract of cubeba officinalis was found to be effective in treating the nephrotoxicity in tacrolimus induced nephrotoxicity.
